eNodeB LMT User Guide
2 Introduction to the eNodeB LMT
2.1 Functions of the eNodeB LMT The eNodeB LMT deploys the eNodeB and identifies and clears faults locally. Use the LMT to operate and maintain the eNodeB in any of the following scenarios: l
When the transport link between the eNodeB and the M2000 is unavailable, use the LMT to start the eNodeB locally.
l
When the eNodeB fails to communicate with the M2000, use the LMT to identify and clear faults locally.
l
When alarms are generated on the eNodeB and related boards must be replaced locally, use the LMT to identify and clear faults. NOTE
When the eNodeB communicates with the M2000 properly, Huawei recommends that you operate and maintain the eNodeB at the network management center (NMC). When you must obtain information from the M2000 for fault identification, the M2000 may fail to provide adequate information because it manages many network elements (NEs). At this time, use the LMT to operate and maintain the eNodeB.
The LMT provides a Graphical User Interface (GUI), which helps users operate and maintain the eNodeB on the web page. It i mplements the following local operation and maintenance (O&M) functions: l
Running eNodeB MML commands
l
Managing eNodeB alarms
l
Running MML commands in batches
l
Tracing messages
l
Monitoring eNodeB performance in real time
l
Software Management
l
Enabling the eNodeB to perform self-test

2 Introduction to the eNodeB LMT
Connection Port Requirements If the computer installed with the LMT cannot visit NEs because of firewalls between them, ports 20, 21, and 80 must be enabled by the firewall. If the computer must visit NEs using the Hypertext Transfer Protocol Secure (HTTPS), port 433 must be enabled by the firewall. Ports 20 and 21 are used for the File Transfer Protocol (FTP). They need to be enabled in the case of file transfer using FTP. Port 80 is used for the Hypertext Transfer Protocol (HTTP) by default. That is, the port is used for a web server by default. Port 433 is used for the HTTPS by default.
Communication Capability Requirements The computer installed with the LMT must support TCP/IP protocols. The minimum effective network bandwidth for the LMT is 512 kbit/s. The recommended value is 2 Mbit/s or larger. NOTE l
The network bandwidth limits the web page opening speed. If the recommended effective bandwidth is provided, the LMT runs fast. If a 512 kbit/s bandwidth is provided, all the functions can be performed but the LMT runs slowly.
l
The effective bandwidth is the bandwidth occupied by the LMT. If multiple applications compete for the bandwidth, the LMT may run slowly even if a 2 Mbit/s bandwidth is provided.
2.3 Components of the LMT Main Window This section describes the components of the LMT main window and the functions of each component.

5 Managing eNodeB Alarms or Events
5.1 Basic Concepts Related to eNodeB Alarm or Event Management Before managing eNodeB alarms or events, you must understand basic concepts related to eNodeB alar ms or events, alarm or event definition, alarm or event log, alarm or event severity, and network management (NM) alarm or event type.
5.1.1 Basic Concepts Related to Alarms or Events This section describes the basic concepts related to fault, event, and engineering alarms.
Fault Alarm A fault alarm is generated when a hardware is faulty or a major function is abnormal. A fault alarm has a higher severity than an event. Based on the status of the faults, fault alarms can be categorized into active alarms and cleared alarms. l
If a fault is cleared, the status of the alarm changes to cleared. This type of alarm is called a cleared alarm.
l
If a fault is not cleared, the status of the alarm remains active. This type of alarm is called an active alarm. NOTE
You can search a database for cleared alarms.
Event Alarm An event notifies users of important information when the system is running properly. Users need not handle an event when it i s generated.
Engineering Alarm l
If an NE is being installed, commissioned, upgraded, expanded, or relocated, the NE is in the engineering state.
l
The following are engineering alarms: alarms reported by physical or logical equipment in the engineering state; alarms that are generated by the peer equipment but are associated with the alarms reported by the equipment in the engineering state; cleared alarms corresponding to engineering alarms.
5.1.2 Alarm or Event Log The alarm or event logs record detailed information about each alarm or event generated by the system. In this way, all alarms or events can be easily queried. You can obtain the detailed information about eNodeB alarms or events from the alarm or event logs. For details about how to query the alarm or event logs, see 5.2.2 Querying Alarm or Event Logs.

5.1.3 Alarm Severity The alarm severity indicates the severity of an alarm. Based on the severity, all alarms can be categorized into four types: critical, major, minor, and warning. Table 5-1 describes alarm severities and handling suggestions. Table 5-1 Alarm severities and handling suggestions
Severity
Definition
Handling Suggestion
Critical
Service-affecting condition. Critical alarms require immediate attention, and must be cleared immediately. For example, faulty devices are repaired or unavailable resources are restored.
Alarms must be cleared immediately. Otherwise, the system may break down.
Major
Degradation of service, not a complete loss of service. Major alarms must be cleared during working hours. For example, device performance and resource performance improve.
These alarms must be cleared in time. Otherwise, some important functions cannot be implemented.

6.1 Overview of Message Tracing The section describes message tracing management functions and the internal process of message tracing.
Functions of Message Tracing Management Message tracing management traces interfaces, signaling links, UEs, and internal messages. It applies to routine equipment maintenance, debugging, and fault location. Tracing functions are as follows: l
Tracing messages over the S1 interface
l
Tracing messages over the X2 interface
l
Tracing messages over the Uu interface
l
Tracing SCTP messages
l
Tracing IFTS messages
l
Tracing CMPv2 messages
l
Tracing MAC messages
l
Tracing IEEE1588 V2 messages
Internal Process of Message Tracing The internal process of message tracing involves creating a tracing task on the LMT and reporting results to the LMT. l
l
Creating a tracing task on the LMT 1.
After you create a tracing task on the LMT, the LMT sends a binary command to the eNodeB to create the task.
2.
The eNodeB allocates an ID to the task and forwards the command to the tracing management module of a specified board.
3.
After receiving the command, the tracing management module records the parameters for tracing contained in the command in the filter table and sends messages to the service processing module.
4.
The service processing module updates the local filter table based on the messages from the tracing management module.
Reporting results to the LMT 1.
After receiving messages from the tracing management module, the service processing module verifies that the parameters in the local filter table are updated. Then, it reports the messages meeting filter criteria to the LMT based on the task IDs contained in the messages.
2.
The LMT analyzes the messages and displays tracing results in the window.

6.8 MAC Tracing This section describes how to trace synchronization status messages (SSMs) and to identify faults on synchronous Ethernet links.
Context l
The channel for synchronous Ethernet messages is the protocol channel of the MAC layer, which is used to transmit SSM messages between Ethernet ports, including clock quality levels. G.8264 protocols define synchronous Ethernet messages.
l
The eNodeB can use the synchronous Ethernet clock as the reference clock to achieve time synchronization. Synchronous Ethernet SSM frames are used to transmit SSM messages between Ethernet ports. If SSM frames are enabled for synchronous Ethernet but the synchronous Ethernet clock does not function properly, t he tracing for SSM frames can be started to view the synchronous status on the Ethernet ports.
Procedure Step 1 In the LMT main window, click the Trace tab. Step 2 In the navigation tree, choose Interface Trace Task > MAC Trace, and double-click MAC Trace. The MAC Trace dialog box is displayed, as shown in Figure 6-7. Figure 6-7 MAC Trace dialog box

6.9 Tracing IEEE1588 V2 Messages This section describes how to trace IEEE1588 V2 messages and to identify faults on IEE1588 clock links.
Context l
IEEE1588 defines the Precision Time Protocol (PTP), which applies to standard Ethernet. IEEE1588 V2 is a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems, which is also called PTPv2.
l
IEEE1588 V2 is mainly used for time synchronization among nodes of the distributed systems. It specifies a mechanism for all nodes to achieve time synchronization using the same reference clock.
l
The eNodeB can use the IEEE1588 V2 clock as the reference clock to achieve time synchronization. IEEE1588 V2 transmits timestamps based on interactions between IEEE1588 messages so that the eNodeB achieves time synchronization. If the IEEE1588 V2 clock does not function properly, the tracing for IEEE1588 V2 messages is started to view the information.
